"They're either afraid to come forward and share information, or are afraid to talk to police officers," Ravenstahl said. "And we want them to know that if they're willing to talk to police officers, if they're willing to share information, if they're willing to come forward, we can provide results like this in their neighborhood."

Chief Nate Harper and other top police brass joined Ravenstahl on Wednesday to announce details of a drug bust in the West End neighborhoods.

Seventeen adults and three juveniles were arrested and charged with drug and gun violations over the course of an eight-month undercover investigation, police said.

Nine of the suspects are reputed gang members from GBK (Greenway Block Killers) and a Beltzhoover group named Zhoove, according to police.

Police said they seized $11,000 worth of heroin, crack and marijuana, plus $10,000 cash and four guns -- two of which were reported and one with an obliterated serial number.
